Lagerita sits somewhere between the beer fridge and the cocktail shaker. The base is a lager brewed to 0.5%, with lime and salt added to give it the sour, saline character that makes a margarita worth drinking. It is a straightforward concept, and it works. The nose is clean and zesty: fresh lime juice, a faint floral hop note. On the palate, crisp lager carbonation opens first, then the salt lifts the lime acidity and the whole thing becomes sharp and mouth-watering. The sour edge is bright without being aggressive. Finish is short and clean, salt and lime hanging just long enough. At 0.5% it does the job it sets out to do. Serve it cold, in a tall glass. A lime wedge is optional but consistent with the brief.
